Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> A bucket made up of iron develops a brown coating after a few months. On the other hand, a bucket made up of plastic remains the same even after years. This shows that plastic is:

• A. Lightweight
• B. Non-reactive
• C. Mouldable
• D. Less expensive

Answer 1

The correct option is B Non-reactive

The bucket made of iron develops a brown coating after a few months due to the formation of rust. It is formed when iron reacts with air (oxygen) and water.

Plastics are generally non-reactive. They generally do not react very easily with air or water. Therefore, the bucket made of plastic remains the same even after many years.
